You want to determine the weldability of your materials with precision

What is weldability

The weldability of a material refers to its ability to be welded reliably, without major defects affecting its mechanical properties or durability. This criterion is fundamental in many industrial sectors - aerospace, automotive, defense, nuclear, medical devices - where assemblies must meet strict performance and safety requirements.

Why assess the weldability of a material?

weldability

Weldability is a critical factor in many industries. Poor weldability can lead to costly failures, production delays and safety issues. At FILAB, we offer state-of-the-art expertise and comprehensive analysis to accurately determine the weldability of your materials, ensuring reliable, long-lasting assemblies.

Why is it essential to determine the weldability of your materials?

Understanding the weldability of your materials is fundamental to :

Optimise welding processes: identify the ideal welding parameters (temperature, speed, heat input) for each material.

Prevent defects: anticipate and avoid common problems such as hot or cold cracking, porosity, inclusions or insufficient mechanical strength.

Select the right materials: choose the materials best suited to your specific welding applications and constraints.

Ensuring compliance: meeting the most stringent industrial quality and safety standards.

Cut costs: reduce scrap, rework and production failures..

FAQ

What types of materials can you analyse for weldability?

We can analyse the weldability of a wide range of materials, including ferrous metals (carbon steels, stainless steels, alloy steels), non-ferrous metals (aluminium and its alloys, copper and its alloys, titanium and its alloys), as well as certain polymers and composite materials where welding techniques are applicable.

What are the most common welding defects that your analyses can help prevent?

Our analysis can help prevent many defects, including :

  • Hot cracking (during solidification of the weld bead)
  • Cold cracking (after cooling, often linked to hydrogen)
  • Porosity (gases trapped in the joint)
  • Inclusions (foreign matter in the joint)
  • Lack of fusion or penetration
  • Fragility of the Thermally Affected Zone (TAZ)
  • Excessive deformation
What role does material characterization play in determining weldability?

Characterization is essential for understanding the chemical composition, microstructure and mechanical properties of the base material prior to welding. This information is fundamental for predicting the behaviour of the material during and after welding, and for interpreting the results of weldability tests. For example, certain alloying elements can increase susceptibility to cracking.

Can the causes of a welding defect be identified in the laboratory?

Yes, in the event of assembly failure, our experts can carry out a complete failure analysis to identify the origin of the problem (contamination, poor preparation, parameterisation, material defect, etc.).
